KA celebrates it's tenth anniversary this year and has provided wonderful entertainment throughout it's residency at MGM, but it has been overshadowed by the other Cirque shows on the strip. The show is alright, but the stage and theatre is gorgeous! You spend the preshow time just staring at the beautiful theatre and metal work.
After an accident last year, they've changed the last big scene. With the new scene the show feels cheap and unfinished. I wish they would rework it to create another impressive ending.
It is worth seeing at a discount, but please go check out some of their other shows if you only have time for one or two shows.
